Grails2和mongodb不工作

我正在使用Grails2.2.0和MongoDB。我已经将Grails配置为针对MongoDB而不是默认的H2内存数据库运行。从错误消息中，h2似乎与此有关，尽管我认为已将其删除

My DataSource.groovy：

grails { 
    mongo { 
        host = "localhost" 
        port = 27017 
        databaseName = "physicians" 
    } 
} 

My BuildConfig.groovy：

plugins { 
   runtime ":hibernate:$grailsVersion" 
   runtime ":jquery:1.8.0" 
   runtime ":resources:1.1.6" 

   // Uncomment these (or add new ones) to enable additional resources capabilities 
   //runtime ":zipped-resources:1.0" 
   //runtime ":cached-resources:1.0" 
   //runtime ":yui-minify-resources:0.1.4" 

   build ":tomcat:$grailsVersion" 

   runtime ":database-migration:1.1" 

   compile ':cache:1.0.0' 
   compile ':mongodb:1.1.0.GA' 
} 

当我想要保存域对象艺术家时，我得到的错误是：

从BuildConfig.groovy

当我这么做的时候，我得到了这个：

| Error Fatal error during compilation org.apache.tools.ant.BuildException: 
java.lang.NoClassDefFoundError: org/hibernate/cfg/Configuration
(NOTE: Stack trace has been filtered. Use --verbose to see entire trace.)

然后我拆下了线

runtime ":database-migration:1.1" 

来自BuildConfig.groovy

搜索解决此问题时未找到最后一部分。这是应该做的吗

您已经卸载了hibernate，因此需要另一个关于mongodb的插件。 你可以加一行

compile ':mongodb:1.0.0.GA'

从BuildConfig.groovy而不是

runtime ":hibernate:$grailsVersion"

---

要在项目中单独使用mongodb gorm，需要注释掉

compile ':cache:1.0.0' 

在BuildConfig中，因为缓存插件依赖于hibernate。您可以在以下内容中找到它：

我不得不从application.properties中删除Hibernate插件，它才能工作。我不确定为什么在应用程序中配置hibernate插件。属性

这是正确答案。仅仅删除compile“：cache:1.0.0”并不能完成这项工作，但添加下一个操作将完成这项工作。

compile ':cache:1.0.0' 

    plugins {
        ....
        runtime(":hibernate:$grailsVersion") {
            export = false
        }
            ....
    }
